Yes, sometimes, they're interchangeable. 作 works for most of cases. It occurs much earlier than 做 in Chinese language history. But now, people prefer to use "做 + concrete noun" while “作 + abstract noun”, here are some examples: 做饭 cook 做蛋糕 make cake 做家具 make furniture 做衣服 make cloth 做作业 do homework 作弊 cheating 作曲 composing 作文 writing 作报告 reporting Generally, 做 is the word extended from 作. it's a little bit hard to distinguish them. It's rather custom than rule playing the role in choosing the correct word. So, use what you see is the best way for this case
